To all whom t may concern.'

Be it known that I, Raa I-Ioaninosworrrii, a citizen of the UnitedStates, and a resident of the town of Grant Park, in the count-y ofKankakee and State of Illinois, have invented certain newand useful Imroveinents in Cnr-Unloading Shovels; an I do hereby declare thatthefollowing is a-full, clear, and exact description of the saine,reference being had to the accompanying drawings and to thev numbers' ofreference inaritcd thereon, which form a. part of this specification.

Many attemptsiiave been made to provide mechanism for quickly andeconomically unloading gondola cars in situations where tipples are notavailable. Such de-` vices have usually proved insnfiicieiit orv un-.satisfactory-for the purpose for which de` signed owing tothe size andwei ht ofthe same, and the difliciilty in han ing. Altliough'attemptshave sometimes been made to utilize. ower shovels for. this such instalations have usually re uire the use of an additional car and a tracparallel to that of the car to be unloaded, and theseI conditions arenot always attainable.

The object of this invention is to provide a power operated shoveladapted for temporary installation upon the carto be-unoaded, andoperated from aportablefpowerplant conveniently located with referencethereto. It is also an object of the invention to afford a constructionand installation which permits ready shiftin other and by the` use owhich the track may be rpiickly cleared for trafila, if'desired. l ieinvention also has Vf'oihita objectan oxceedingly compact and simpledevice ffor the purpose specified inl whicliltlie `shovely' althoughcarried upon a veryshortdipper stick or frame, may be swung laterallyofthe-car sufficiently to deposit wellcleairofl the car. 1 It is also anobject of the inventionto ail'ord in a device ofthe class describedan;`

improved bottom dump shovel` whereby, the

lischargefrom the shovel maybe :delivered with accuracy to any. suitable.-placefot deposit or vehicle to receive the saaie. i

It is also an object of the 4invention to aflord a construction wliereb,the entirede'- vico maybe quickly elevate from lthaicar lo permit theremoval et the unloaded cui pur ose,-

'It is unimportant object of the invention to accomplish the urposcsabove'sct foi-lh with the least possible obstruct-ion of track and aminimum expenditure for labor and power.

It .is also an important object of the inventionl to afford aconstruction whereby the dipper may be moved longitudinally thc car bymeans of suitable ri ging for that purpose, and in which the device isat all times under perfect control during any of its operations.

The invention consists in the matters hercinafter described and morefully pointed lout and defined in the appended claims.

As shown in the drawings: the car, as indicated b '1, is an ordinarygondola car of any kin or construction. On' each side of said car atabout opposite the middle of the car, and at unloading osition, areerected gin poles 2 and 8, `w iich are guyedin upright position by meansof side guy lines 4, as shown in Fis. 1 and 2 and areeonnected at thetop y means oi a main lhorizontal stay or cable l5, at asuilicient'height above the vtrack to permit standard traiiic to passbeneath the same. One of said gin poles is positioned near the trackwhile the other vvis at a sufiicient distance from the track to permitthe entiremachine when supported on the main stay 5, to'be movedlaterally to clear the track for traffic, as shown in Figs. 1 and 2.Side sills 6, of a len th equal to the length ofthe longest car geunloaded, are secured one on'each side sills are provided 'at intervalsin their len h with sill hooks 8, rigidly secured by bolting orotherwise on the underside thereof,as

.shown in Figs. 3 and 14, and shaped to en- 30` gage over the top ofsaid side-board of the car as shown in Fig. 14. Said hooks,8,'are eachprovided with a ring 9, at the outer end thereof, with whichisconnectedfachain'; 10, whereby the sills are secured to the track.

'For this purpose, the chains, as'shownarei assed throu heye bolts 10',secured'each' in the 'end o a tie and the end of achaiiii having passedthrough'asaid eye"-'bolt,'{isdrawn upwardl and connected-with a bentlever, one 'end 1 'of which is securediny a' link of said chain, andfthe other-end 12,l thereof is swung u wardly alongside the chain 'andsecured t ereto bymeans ofi-a link 18,' slidable on the'chain, theend ofthe chain, of course. serving asthe lfulcrum'for thelever. lWhile I haveshow".-eye"bolts" secured to the ties, asfthe means forgatt'ach''4-` ingthe chains thereto, of course, the `attachi' ment with the track may beotherwisefetectgf ed, as, for-instance the'attachmentlina bef madedirect with the'railgif` referre ,for in anysuitable mannertoatiorattafchrnentl upper edges "oi p tli'e; sills, #6," aref -chani'feredf orcutjaway'or'if'each side 'andlsecured on the". top of eachsilla'ii'dextendin 'forithe'len'gtlr thereof is a'metallic band; 4 theedges'of which proj e`ct over,y the' chami'ered. edges 'of'tlie'sills,'as shown in*Fig.'-14.

Thisconstruction permits the si( e and end sills to be adjusted to fit thewidth and length of anv gondolacar.

A' line100, leads -through a lock 101, supported by a carriage' 105,' on-tliemain horizontal stay 5, on .-the gin pole.4 and through a block 102, asshowninFigs- 1- and 2,'the latter of which -engatges hoisting lines 103,asshown in Figs.

thencetothe hoisting engine, as before de- 'scribed.jAs shown in Fig.A1, asnub line 100,

is attached to the carriage'lO, and passed through either of t-he snatchblocks 107, on vthe upper ends of the gin poles 2 and 3, and lthensecured on cleats 108, on said gin poles.

The operation is as follows: The machine may be assembled on the groundin the space between lthe trackand the gin pole.3, and then hoisted onthe car by means of the blocks 101-102, and hoistin line 100, or

Amay be'assembled on the car in the first instance. The side sills are,of course, adjusted the required distance adapted to fit on thoside-boards of the carv and the -end sills are secured thereto as,beforedescribed appropriately, and this Qadjustment is readilyfacilitated by the arrangement of holes at the ends of said sills whichare so arranged as to adapt the ad- `justment for any of the standardgondola sizes. The machine having been assembled in position, it isdrawn as far as possible to t e rear end of the car, as for instance. tothe position shown in Fig. ings, the di per previous y the ratchet 2, ofthe drawsupported upon )ars in any of the positions indi- ,oated indotted lines in Fig. 4, is then drop ed into loading position, as shownin :full mcs in said figure by the release of said ratchet bars fromtheir detente by the operator pulling u ion the actuating rod 84. lu

this position he machine as a whole is d rawu forwardlyto draw thedipper into the work, for this purpose the line 90, being utilized andthe-operator holding the dipper from ing on its table by ap ilving his.lweig it upon the footpiece 39". Vhen said 4dipper has been drawnsuiiiciently into the work or simultaneously with such forwardlmovement,jthe 1ine.69, is applied to the hoistin drum, the etl'ectbeing if the operator sti holds `said table from turning, to .elevatethe d pen-,andthe operator having released vthel -dotent from thefriction .drum I,169, the,.dipper swings ,tloQtheV osition shown'.in'thefjupperdotted lines in ig. 4.

Withtieupward movement. of tic di iper, the ratchet bars have, fof course, sli(upwardly over the detcnt'sthere'- for on the frame to the osition shownin dotted lines in Fig. 4, an support the'dipper during the ateral swinthereof to dumping position, and after-t ie release'fof the line G9, onthe hoisting drum, continue to support the dipper until it is returnedover the car.- The reverse movement is"accomplished by means oft-hezline` 93,--"'1`hc dipper is new supported over the car inthe'position shown 1n any of the dotted lines shown in Fi 4.
